Adafruit Pycom LoPy4 [ADA3689]

With so many connectivity options, Pycom's LoPy4 is a lot like an amazing, multi-course brunch. You've got LoRa playing your favorite morning public access radio station, WiFi talking to your smart coffee maker, SigFox and cream cheese on a bagel, and a baker's dozen of Bluetooth muffins-- I mean, blueberry muffins!

Boosted with the Espressif ESP32 chipset, the LoPy is one of the fanciest quadruple-threat MicroPython-enabled microcontrollers. The wide choice of transports provides full flexibility during testing, install, deployment and even later when you want to switch how you send your data around. The LoPy4 has a built-in operating system that supports MicroPython, the lightweight cousin of the Python web programming language. You can use this board as is, or develop your application, then minimize the design with one of the smaller and simpler Pycom boards (if, say, you realize you don't need SigFox or LoRa)

Comes with just the dev board. You'll need an antenna for LoRa/SigFox, using LoRa/SigFox without an antenna can damage the board! An external antenna is recommended for WiFi/BLE (which has a ceramic antenna built in).

Processing

– Espressif ESP32 chipset– Dual processor + WiFi radio System on chip– Network processor handles the WiFi connectivity and the IPv6 stack– Main processor is entirely free to run the user application– An extra ULP-coprocessor that can monitor GPIOs, the ADC channels and control most of the internal peripherals during deep-sleep mode while only consuming 25uA
